Electrostatic Force curved beam

  1. Jun 10, 2010 #1

    I'm trying to figure out what the electrostatic force between a curved beam (see picture attached) and a standard parallel plate electrode would be. I have an equation for the critical force to induce snapping between the bi-stable states of the beam, but I need to find out one for electrostatic force to induce this snapping.

    I know how to obtain the electrostatic force for 2 parallel plates, but when the beam is curved I'm having an issue. Can someone point me in the right direction here?

    Thanks so much!

    For infinite plate electric field does not depend on distance.
